"Many of our supporters criticised us for that too. I felt I should've taken a stand, but I didn't.
"I started getting a hollow feeling in my stomach and thought 'today I'm saying goodbye to the world'. I called my wife and told her I felt as if I were drowning, but didn't know why. She said I should come home immediately."
The Lions went on to score a surprise win over the Chiefs under the guidance of assistant coach Ivan van Rooyen
At the time, it was reported de Bruin had returned home because of a "serious medical condition".
A South African media outlet claimed the team's poor form had led to a "nervous condition". De Bruin had also denied a claim he was in conflict with senior players before the Chiefs game.
One Lions fan said on Facebook "It takes a real man to admit when all is not well! Hats off to our coach. Glad to see him back."
But another said: "He knew when about that fixture long ago."
There was also a complaint about de Swys describing the Lions as a Christian team.
"It also has those of other (beliefs) and no belief," the fan reckoned.
